Word and Excel files open automatically in their respective Microsoft programs, but PDFs are different. Browsers can display them just like they can display web pages. In fact, if your computer opens PDFs on a web browser by default, you\u2019ll even see your web browser\u2019s icon next to the PDF:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1010\" height=\"275\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image2-1.png\" alt=\"A Windows finder showing a file called mypdf and Open options to Share with Skype, Move to OneDrive and more, including Open with.\" class=\"wp-image-7841\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image2-1.png 1010w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image2-1-300x82.png 300w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image2-1-768x209.png 768w\" sizes=\"auto, (max-width: 1010px) 100vw, 1010px\" \/><\/figure>\n\n\n\n<p>How to view a PDF using your browser:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open your browser (Chrome, Firefox, Edge, Safari, etc.).<\/li>\n\n\n\n<li>Drag a PDF from <strong>File Explorer<\/strong> (or its location) into the window.<\/li>\n\n\n\n<li>The file will open in a new tab.<\/li>\n<\/ol>\n\n\n\n<p>Even though it\u2019s in a browser tab, you\u2019re still viewing a file from your computer.

PDF editors have more features for you to tweak or edit a PDF, but they will be limited when compared to the original document editor. The PDF format is best for light editing, annotations and other changes.&nbsp;<\/p>\n\n\n\n<p>Editors in action:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Preview (Mac) can handle light edits like merging, splitting documents.<\/li>\n\n\n\n<li>Adobe Acrobat (paid) handles advanced edits like editing a PDF\u2019s security or metadata.<\/li>\n\n\n\n<li>PDF.Live, which works entirely online, covers editing text, signing, commenting, converting, merging, and more.<\/li>\n<\/ul>\n\n\n\n<p>To edit with PDF.Live: Visit the <a href=\"https:\/\/pdf.live\/convert-pdf-into-editable-pdf\">PDF.Live editor<\/a>, drag your file into the window, and start making changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Browser Tools You Can Use While Viewing<\/strong><\/h2>\n\n\n\n<p>When you open a PDF in your browser, you\u2019ll usually see:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A print icon<\/li>\n\n\n\n<li>A download button<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"406\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image3-1.png\" alt=\"A document with lorem ipsum text in a browser window.\" class=\"wp-image-7843\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image3-1.png 850w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image3-1-300x143.png 300w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/11\/image3-1-768x367.png 768w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><\/figure>\n\n\n\n<p>The print dialog also gives you the option to <strong>Save as PDF<\/strong> rather than printing a physical document, which is helpful if you only need specific pages from a larger document.
